The former Borussia Dortmund star has made a splash in his brief spell with Wenger's men, and spoke about the differences between the Frenchman and the Portuguese ahead of Arsenal's weekend derby against Tottenham.

"Arsene Wenger is friendlier, he understands, can think about players' situations, is calmer. That's the difference."

Signed for around £37 million in the summer of 2016, Mkhitaryan helped United to three trophies during his time at Old Trafford, which included scoring a goal in the Europa League final triumph over Ajax last spring.

After a hot start, he lost his place in the starting XI toward the middle of the current campaign. But the Armenia international is proud of his body of work at the club.

"I think I left an impression in Manchester, although I had difficulties," he added.

"We won three trophies in a year and a half, it's not every club that does that.

"We won the Europa League final, I scored a goal. If people say that I have not had enough success it is their opinion, but I can say that I had a lot of success at the club."
